What is the Fifth Amendment?

The Fifth Amendment reads in full: 'No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger; nor shall any person be subject for the same offence to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation.' Ratified December 15, 1791 as part of the Bill of Rights, the Fifth Amendment is distinctive in that one of its five clauses -- the grand jury requirement -- has never been incorporated against the states. In Hurtado v. California, 110 U.S. 516 (1884), the Supreme Court held that the Due Process Clause of the 14th Amendment does not require states to use grand juries for felony prosecutions; states may instead proceed by information, a formal written charge filed directly by a prosecutor. Every other Bill of Rights guarantee that has been incorporated against the states was incorporated through the 14th Amendment. The double jeopardy clause was incorporated against the states in Benton v. Maryland, 395 U.S. 784 (1969), and the self-incrimination clause was incorporated in Malloy v. Hogan, 378 U.S. 1 (1964), making both rights binding on state and local governments as well as the federal government.

The double jeopardy clause bars the government from subjecting any person to a second prosecution for the same offense after an acquittal, a second prosecution after a conviction, and multiple punishments for the same offense in a single prosecution. The protection attaches when jeopardy begins -- in a jury trial, when the jury is sworn in; in a bench trial, when the first witness takes an oath. The Supreme Court defined the 'same offense' question in Blockburger v. United States, 284 U.S. 299 (1932): two charges constitute the same offense unless each requires proof of a fact that the other does not -- the 'same elements' test. A critical limit on the double jeopardy clause is the dual-sovereignty doctrine: because the federal government and each state are separate sovereigns, each may prosecute the same underlying conduct under its own laws without the second prosecution being barred by double jeopardy. The Supreme Court reaffirmed the dual-sovereignty doctrine in Gamble v. United States, 587 U.S. 678 (2019), an 8-1 decision written by Justice Samuel Alito. The dual-sovereignty doctrine has direct practical significance when the same conduct gives rise to both federal and state charges, because a presidential pardon of federal charges does not foreclose state prosecution for the same underlying acts.

The self-incrimination clause gives every person the right to refuse to be a witness against himself in a criminal case. The privilege applies to compelled testimonial communications -- it does not protect against compelled production of physical evidence such as blood samples, DNA, handwriting exemplars, or voice recordings. The most consequential application of the self-incrimination clause is Miranda v. Arizona, 384 U.S. 436 (1966), where Chief Justice Earl Warren wrote for a 5-4 majority that the Fifth Amendment privilege is imperiled by the inherently coercive atmosphere of custodial interrogation. The Court held that before questioning a person in custody, police must advise them: that they have the right to remain silent; that anything they say can and will be used against them in court; that they have the right to an attorney; and that an attorney will be appointed if they cannot afford one. A suspect who receives these warnings may waive them and speak, or may invoke the right to silence or the right to counsel, at which point questioning must cease. In Berghuis v. Thompkins, 560 U.S. 370 (2010), the Court held that invoking the right to silence is not automatic -- a suspect must affirmatively say so; simply remaining silent during questioning is not itself an invocation. The self-incrimination clause applies in any legal proceeding -- not only criminal trials -- wherever the answers could expose the speaker to criminal liability, including grand jury appearances and congressional hearings.

The Due Process Clause of the Fifth Amendment prohibits the federal government from depriving any person of life, liberty, or property without due process of law. It operates as the counterpart to the Due Process Clause of the 14th Amendment, which imposes the same requirement on state and local governments (ratified 1868). Courts have recognized two dimensions: procedural due process requires that the government provide fair procedures -- notice, a meaningful opportunity to be heard, and a neutral decision-maker -- before depriving a person of a protected interest. Substantive due process holds that some governmental deprivations are unconstitutional regardless of the procedures used, because they impinge on fundamental rights. The Takings Clause -- the final clause of the Fifth Amendment -- provides that private property shall not 'be taken for public use, without just compensation.' The federal government's power of eminent domain derives from sovereignty; the Takings Clause constrains but does not eliminate it, imposing two requirements: the taking must serve a public use, and the owner must receive just compensation, which courts define as fair market value -- what a willing buyer would pay a willing seller in an arm's-length transaction. In Kelo v. City of New London, 545 U.S. 469 (2005), the Supreme Court held 5-4, in an opinion by Justice John Paul Stevens, that the city's plan to condemn private homes to make way for an economic development project -- office buildings, a hotel, and retail space planned in connection with a Pfizer research campus -- satisfied the public-use requirement. The decision produced a significant legislative backlash; within several years, more than 40 states enacted statutes or constitutional amendments restricting the use of eminent domain for economic development purposes.

The Fifth Amendment's regulatory takings doctrine asks when a government regulation so severely burdens property that it amounts to a taking requiring compensation, even though the government does not physically take the land. The foundational regulatory takings case is Penn Central Transportation Co. v. New York City, 438 U.S. 104 (1978), which upheld New York City's historic landmark designation of Grand Central Terminal as a regulation that did not constitute a compensable taking. The Court established a three-factor balancing test: the economic impact of the regulation on the claimant; the extent to which it has interfered with the owner's distinct investment-backed expectations; and the character of the government action -- whether it is a physical invasion or only a restriction on use. Loretto v. Teleprompter Manhattan CATV Corp., 458 U.S. 419 (1982), established a per se rule: any permanent physical occupation of private property by the government is a taking requiring compensation, regardless of its economic impact. Lucas v. South Carolina Coastal Council, 505 U.S. 1003 (1992), established a second per se rule: regulations that deprive the owner of all economically beneficial use of land are takings requiring compensation, subject only to background principles of state property law. The Penn Central balancing test, the Loretto physical-occupation rule, and the Lucas total-deprivation rule together form the governing framework for regulatory takings claims, which arise frequently in disputes over environmental rules, zoning, wetlands regulations, and other land-use restrictions that limit how owners may use their property.

For the 2028 presidential election, the Fifth Amendment is relevant across several active debates. The self-incrimination clause and grand jury process are central to high-profile federal criminal prosecutions that have shaped the political environment; the dual-sovereignty doctrine determines whether a federal pardon of federal charges forecloses state prosecution for the same underlying conduct, a question of direct practical importance when federal and state charges arise from the same acts. The Miranda warning requirement and proposals to narrow or expand it intersect with law-and-order and criminal-justice-reform positions that candidates hold on policing and civil liberties. The Takings Clause and the law of eminent domain bear on major infrastructure projects -- pipelines, highways, border facilities -- that require the government to acquire private land. Regulatory takings doctrine shapes constitutional challenges to environmental regulations, wetlands protections, and zoning restrictions that restrict property owners' rights. The 2028 winner will appoint federal judges -- potentially including Supreme Court Justices -- who will apply Fifth Amendment doctrine in all of these areas for decades to come.
